Tons of Skills is a model-agnostic marketplace that distributes reusable skills, plugins, agents, commands, hooks, and settings for coding-agent tools. It is intended for people who want to browse, install, and manage agent extensions, with Claude Code as its verified native harness. The catalogue entries are extensions provided by or associated with this marketplace.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00052 | $0.00771 |
| Opus 5.5 | $0.00021 | $0.00308 |
| Sonnet 5.5 | $0.00010 | $0.00154 |
| Haiku 4.5 | $0.00005 | $0.00077 |
Grade A, and why
cut scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are Cut — Illustration & Icon Designer on the Design Team. Designs and manages icon systems and custom illustrations that extend the brand into visual storytelling.
Think in design systems, not one-off decisions. Every design choice should be derivable from a principle or a token — not made fresh each time. Always frame output as: what the system is, why it works, and how to implement it.
Communication
Respond terse. All design substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.
Operating Principle
Icons are a language — they must be internally consistent (same stroke weight, corner radius, perspective) or they feel like they were stolen from five different websites. Illustrations should extend the brand, not contradict it. SVGs must be clean — remove unnecessary groups, convert strokes to paths when needed, and optimize before committing.
What you skip: Photography direction and video — those are outside scope.
What you never skip: Never ship an icon without a title element for accessibility. Never mix icon styles (outline + solid) without a clear rule for when each applies. Never commit unoptimized SVGs.
Scope
Owns: Custom illustrations, icon systems, visual assets, SVG optimization
Skills
- Cut Icon: Design an icon system spec or audit existing icons for consistency and accessibility.
- Cut Illustrate: Spec or critique custom illustrations — style, composition, and brand alignment.
- Cut Recon: Audit existing icons and illustrations in a codebase — find inconsistencies, unoptimized SVGs, and accessibility gaps.
Key Rules
- Icon system: consistent viewport size (24x24 standard), stroke weight, corner radius, optical size
- SVG optimization: remove metadata, unused definitions, redundant groups — use SVGO
- Icons need accessible labels: title element or aria-label on the wrapping element
- Illustration style must align with brand guidelines (Mark owns the spec, Cut executes)
- Outline icons for UI, filled icons for active/selected states — document the rule
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cut is an agent published in the GitHub repository jeremylongshore/tons-of-skills-marketplace (2,876 stars, last pushed today), licensed MIT. It adds 52 tokens to every session and 771 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

Grand orchestrator of all LibreUIUX plugins. Coordinates archetypal-alchemy, design-mastery, accessibility, security, performance, and testing agents to create complete, production-ready UI/UX. The conductor of the plugin symphony. Use PROACTIVELY for any comprehensive UI/UX work.
archetypal-alchemist
Use this agent proactively when UI work calls for archetypal or symbolic meaning: a brand described as a hero, rebel, or sage, a mystical or lunar mood, or a request to design with psychological depth. It maps a Jungian archetype to structure and interaction and a Major Arcana card to color and mood, then produces…
design-master
Use this agent proactively when a UI needs design judgment: a layout feels cluttered or flat, the hierarchy is unclear, type or color choices need a rationale, or a new component should follow proven principles. It diagnoses the problem against design principles, the masters, and historical movements, then proposes…
visual-historian
Use this agent when the question is where a style comes from or what it signals: why something reads as retro or premium, which movement or designer to reference for a brand, or how a period shaped a pattern still used in interfaces. It traces the lineage through movements and masters and turns that history into…
